Orbi main connecting to 1 satellite at 5ghz, 1 @ 2.4; 1 PC at 5 ghz, 1 (same room) 2.4

[CR-sound]

rbr 50, firmware 2.0.0.74

rbs 50, current firmware

1 satellite is at 5ghz, 1 at 2.4...both used to be 5ghz

2 PCs (Windows 10, all upgrades applied, including 'Creative') in the same room as rbr, both ac capable, both used to run 5ghz, now 1 at 5, 1 at 2.4

Thoughts?

A shot in the dark, perhaps, but try unchecking the "Enable Daisy-Chain Topology" box in the web GUI under Advanced>>Advanced Setup>>Wireless Settings.
